Summary
A new "Trap and Occlude Technique" simplifies retrograde wire externalization for coronary chronic total occlusions (CTO) percutaneous revascularization. This method aims to enhance procedural efficiency and patient safety.
Area of Science:
- Interventional Cardiology
- Cardiovascular Surgery
- Medical Devices
Background:
- Percutaneous coronary intervention (PCI) success rates for coronary chronic total occlusions (CTO) have improved with retrograde approaches.
- Developing efficient techniques for retrograde wire externalization remains crucial for CTO revascularization.
